Transcript for Clip 1 -- Bio-Prospecting
The way we actually find these enzymes [is to] go out and do
bioprospecting. Genencor has a little tag line "innovative by nature" and
what we mean by that is there's so much actually out there in the world, in
terms of biodiversity. I came across a fact recently where we've only
studied 1% of the organisms out there. Ninety-nine percent we haven't
even touched yet. It's that biodiversity weÕre tapping into. We go out and
look at thermal vents in national parks, bat caves in Mexico. We harvest
samples to see what kind of microoganisms exist in there and look at
what kinds of enzymes they produce . We test those in a variety of
applications to see if they give us any kind of beneficial effects our
customers might like to seeÉ. For instance, if you have a certain kind of
stain, [a chocolate stain], does this enzyme work effectively against a
broad range of stains in certain conditions? It can work in hot water. It can
work in alkaline conditions. We look to see whatÕs out there in the wild and
bring that back to the lab. If that enzyme is what we're looking for, then
we can actually put it into a production host, a little organism that will
produce it efficiently and then we bring it back to the plant and we put it in
a very controlled environment, inside of a tank, and grow those cells up
under controlled conditions of temperature and pressure and things like
that. And that makes the enzymes force which we then harvest.
Transcript for Clip 2 -- Cleaning up with GE:
The reason we've gone to enzymes to help in detergents is it really provides
beneficial
effects not only for cleaning but also in the environment. If you look back in
the '60s
and '70s...there were a lot of phosphates and surfactins in the detergents.
And that
caused a lot of environmental problems. Because when that water went out into
the
streams, it would cause things like algae blooms, which took all the oxygen
out of the
water and then the fish would die. With the enzymes now we get the same
cleaning
effect without the phosphates. And that's very beneficial because now you have
a very
good way to get your clothes clean and also not have a negative environmental
effect.
